Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Q1
In the cloning vector pBR322, if a foreign DNA fragment is inserted at the BamHI site within the tet^R gene, what will be the antibiotic resistance phenotype of recombinant transformants?
क्लोनिंग वेक्टर pBR322 में, यदि tet^R जीन के भीतर BamHI साइट पर एक विदेशी डीएनए टुकड़ा डाला जाता है, तो पुनः संयोजक ट्रांसफॉर्मेंट्स का एंटीबायोटिक प्रतिरोध फेनोटाइप क्या होगा?
A
Tetracycline-resistant and Ampicillin-sensitiveटेट्रासाइक्लिन-प्रतिरोधी और एम्पीसिलीन-संवेदनशील
B
Resistant to both Ampicillin and Tetracyclineएम्पीसिलीन और टेट्रासाइक्लिन दोनों के लिए प्रतिरोधी
C
Ampicillin-resistant and Tetracycline-sensitive (amp^R tet^S due to Insertional Inactivation)एम्पीसिलीन-प्रतिरोधी और टेट्रासाइक्लिन-संवेदनशील (सम्मिलन निष्क्रियता के कारण amp^R tet^S)
D
Sensitive to both Ampicillin and Tetracyclineएम्पीसिलीन और टेट्रासाइक्लिन दोनों के प्रति संवेदनशील
Correct Answer: Option C
Explanation:
Inserting foreign DNA at the BamHI site disrupts the open reading frame of tet^R (insertional inactivation), rendering recombinants tet^S while retaining intact amp^R.
BamHI साइट पर विदेशी डीएनए डालने से tet^R (सम्मिलित निष्क्रियता) के खुले रीडिंग फ्रेम में बाधा आती है, जिससे अक्षुण्ण amp^R को बनाए रखते हुए पुनः संयोजक tet^S प्रदान किया जाता है।
Q2
How does Blue-White screening using the \(\beta\)-galactosidase (lacZ) gene simplify the selection of recombinant clones over dual-antibiotic replica plating?
\बीटा-गैलेक्टोसिडेज़ (lacZ) जीन का उपयोग करके ब्लू-व्हाइट स्क्रीनिंग दोहरे-एंटीबायोटिक प्रतिकृति चढ़ाना पर पुनः संयोजक क्लोन के चयन को कैसे सरल बनाती है?
A
Recombinant colonies are White (due to insertional inactivation of lacZ), while non-recombinant colonies are Blue in the presence of chromogenic X-gal substrateपुनः संयोजक कालोनियां सफेद होती हैं (लैज़ के सम्मिलन निष्क्रियता के कारण), जबकि गैर-पुनः संयोजक कालोनियां क्रोमोजेनिक एक्स-गैल सब्सट्रेट की उपस्थिति में नीली होती हैं
B
Recombinants turn bright blueपुनः संयोजक चमकीले नीले रंग में बदल जाते हैं
C
Non-recombinants fail to grow completelyगैर-पुनः संयोजक पूरी तरह से बढ़ने में विफल हो जाते हैं
D
Recombinants emit green fluorescenceपुनः संयोजक हरी प्रतिदीप्ति उत्सर्जित करते हैं
Correct Answer: Option A
Explanation:
Insertion of foreign DNA into the lacZ coding sequence inactivates \(\beta\)-galactosidase; non-recombinants produce active enzyme cleaving X-gal into blue product, whereas recombinants form white colonies.
लैक्ज़ कोडिंग अनुक्रम में विदेशी डीएनए का सम्मिलन बीटा-गैलेक्टोसिडेज़ को निष्क्रिय कर देता है; गैर-पुनः संयोजक सक्रिय एंजाइम का उत्पादन करते हैं जो एक्स-गैल को नीले उत्पाद में तोड़ते हैं, जबकि पुनः संयोजक सफेद कॉलोनी बनाते हैं।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
